In Japan, a minor refers to someone under the age of 20, which is the legal age of adulthood in the country. When it comes to politicians in Japan, there are specific legal requirements and age restrictions for holding certain political positions.

Legal Age Requirements for Japanese Politicians:

1. National Diet (Legislative Body):

   • Members of the House of Representatives (lower house) must be at least 25 years old to run for office.
   • Members of the House of Councillors (upper house) must be at least 30 years old to run for office.

   This means that politicians who are under the legal age (i.e., minors under 20) are not eligible to hold a position in the National Diet, including as a member of the House of Representatives or the House of Councillors.

2. Local Politics:

   • For local elections, the legal age varies. For example, to run for mayor or a local assembly seat, candidates typically need to be at least 25 years old, although the exact age requirement can vary depending on the municipality.

3. Exceptions:

   • While there may be cases where young individuals have become involved in political movements, activism, or leadership roles within local party structures, holding an official elected position requires the individual to be above the minimum age established by law.

Can a Minor Become a Politician?

In short, no, a person under the age of 20 in Japan cannot hold an elected political office in the National Diet or most local government positions. However, young individuals may be involved in politics in other ways, such as through youth wings of political parties or through activism, but official political roles require meeting the age requirements.

In the broader context, some countries have youth parliament programs or similar initiatives that allow young people to engage in political discussions and decision-making in a simulated or advisory capacity, but these do not carry the same legal responsibilities or powers as actual elected offices
